Family photographer

[Warrigal]

My son in law is a freelance photographer.
He recently posted this photo on Facebook.

I'm still tying to work out how he captured this image.

Is she lying on her back?

I don't think so. Look at her hair. It is subject to gravity aligned to her body.
I think she might be in the act of leaping up. She is a dancer, I believe.
